VENTILATOR.

Application led. September 21, 1923. Serial No, 663,940.

My invention relates to ventilators of the class used in motor vehicles, trains and the like and is designed particularly with reference to supplying fresh air within the enclosure and at the same time to draw impure air therefrom.

It is also an object of my invention to provide mechanism for screening the incoming` air which has been found particularly desirable when the device is used in train service, also to provide means for adjusting the size of the opening controlling the inletI of fresh air, and to so arrange the device that this adjustment may easily he made by the occupant of the car.

These and other objects of my invention, which will beapparent to those skilled in the art, are set forth in the following description and claims In the accompanying drawings, I have illustrated what I now consider an embodiment of the essential features of my invention and in these drawings Figure l is a longitudinal plan section of the same,

Figure 2 illustrates in elevation a section of the ventilator applied to car,

Figure 3 is a transverse section taken on line 3 3 vof Fig. 2 and Figure 4is a. similar section taken on line 4-4 of Fig. 1.

Referring to the drawings, A represents a casing forming an air duct or channel which is preferably tubular and open at both ends. The ends of thiscasing are preferably cut upon an angle diagonal to the axis thereof with the long sides of the tubes upon the outside as shown at a-`-a, to facilitate the passage of air through the channel.

Upon the inside, or what I shall designate the short side'a o'f the channel, I provide an opening by cutting a slot lengthwise ofthe channel casing and bending the sides thereof at right angles, or cutting the bent portion out entirely, to form a central longitudinal opening intofthe air channel casing A. Fittedy into this opening is a longitudinally extending'A casing B, having two sides and end walls closed and the two opposite sides open, one of which extends into the aforesaid opening formed in the air channel casing. A

This casing B forms an airway having open communication with the tubular 'channel A into which fresh air enters through the end openings thereof and finds its way into the interior of the cai'.

A supporting frame member C receives one side of the casing B, thereof. This supporting frame is provided with an opening" extending through the longitudinal center thereof, one side of said opening receiving the casing B, which is referred to and the opposite side opening into the interior of the car.

`Sliding doors @-02 are provided to close the openingl b, These sliding doors are held in guideways formed by the clips 0-c, suitiblyCattached tothe supporting frame-inein- Jer Screens D--Dv are secured tothe casing B extending over the opening throughl said frame to the inside of the car. These screens are preferably of line mesh to prevent dust, fiying particles and the like from passing through 'the window to the interior of the car. 1

Extending transversely of the casing B are a plurality of stationary partition walls, the central partition E lbeingl straight and positioned mediate the length of said casing. This partition E is secured at the edges .thereof to the side wall of the casing B.

the lower edge of said partition meeting the center of the screen covering D over the inlet air passageway and the screen D covering the outlet air passageway.

Arranged upon opposite sides of this central partition E are other partition or dividing walls FIL-E2, the side edges of which are also secured to the wall of the casing'` B. The partitions E-E2 are curved from end to end thereof, forming a concavo-conrex wall curving from end to end thereof. the concave side of each of said walls TEL-E2 being turned toward the open ends of the casing A, 'forming' Yan air channel therethrough. .It will ybe observed that these curved walls extend at the bottom thereof to the screens D-D above the sides of the wall of the casing B, but not in contact with the `wall forming the air ohannelxcasing A. These partition walls extend at different lengths from the screen"through the casing toward the wall of the tubular member A, and form deflectors or guides for the air 'currentspassing into or out ofthe car. The

curve on the lower end of each partition E--E2` will cause an air current or eddy to form in each compartment between 4rthe partitions and casing-AB, causing Aany dust Vor small particles flying in the air to be deflected into the lowermostpart A of the air charnel or casing A. The current of air passing directly through said channel ifi when the vehicle is moving will carry any dust or iiying particlesthrough the channel to atniosphere c The supporting lframe C is provided with a longitudinally fentending recess upon one side thereof which is linedwith `felt or other more or less Vtiexiblc material F, `which re cess when the device is placedv in position receives the Vglass 'F' forming vthe window of the car, or it mayreceive a frame *holding said glass in the window as one which is set'in a frame.

G is a section of the frame or'window'sash within which the ventilator is placed.

Nhenthe device is assembled andpl'aced inposition, the screen openingsareupon the interior of thecai. These openings may be closed by drawing the sliding .doors (3Q-C2 together in the position shown in dotted lines in Figure l; Then a Circulation of air is desired :inthe car', the door'sGi-C2 are opened, fresh air is drawn into the ai'r channel A, through the end of the ventila tor extending' Ain theV direction of `travel of the car and as the air current passes through the opening a2 or a3, it strikes the partitions Elf-E2 in said channel andis de- Iiected toward and through the screen openings into the car; any dust or cinders entering the air channel will Strike the partitions P3L-E2 and vfall to the bottom of the easing B, and out through the opening B2.

The screen opening extending toward the rear of the car in the direction of its travel, permits the air within the carto pass out through said screen opening vand between the partition E or E2 into the air channel A and out to atmosphere at the rear of the ventilator.

It will be seen that I have provided a ventilator which is in one compact structure the inlet and "exhaustl opening automatically operating though the 'car is Inoving forward or backward; and the lmeans for regulating the size of the inlet andlexhaust openings is 'positioned 'within the -inside of the car making convenient for the occupant to open or close the saine as desired.

I have also shown and vdescribed a ventilator provided with ai plurality of partitions spaced apart in the casing between the air channel and supporting member, but Iconteniplate the use cfa ventilator having but one central partition E, the incoming' air being `diverted from said partition "through the opening tinto the interiory of the'car vand the impure air from the car exhausting through the opening upon the opposite side ofthe partition.
